Drivers are warned to expect a short delay getting across the Bay Bridge on Saturday as Caltrans implodes the last two piers of the old span, officials said.

Caltrans has scheduled the implosion for between 6 a.m. and 8 a.m. to line up with the bay’s slack tide, officials said, a short period where the water is completely free of tidal movements.

Alejandro Lopez, a spokesman for Caltrans, said the California Highway Patrol will halt traffic at the metering lights on the east side of the bridge and conduct a rolling stop on the west side when the implosion occurs.

“While we do the implosion, we don’t want drivers to be distracted,” Lopez said. “It’s a few minutes and everybody can continue with their weekend.”

The two final piers will come down a day before the Bay Bridge’s 81st anniversary — it first opened to traffic on Nov. 12, 1936. The pier demolition will be completed a year ahead of schedule, officials said, saving nearly $10 million.

A live stream of the demolition will be available on the Caltrans website on Saturday.
